12 Claims. (Cl. 219-40) Our invention relates to Vaporizers, more parsleeve 13 and two or more apertures 13 articularly of theelectric type such as disclosed in ranged around said sleeve. Movably mounted in United States Patent #1,663,558. said sleeve 13 is the stem 14 of a valve body 14 One object of this invention is to provide the adapted under the action of a spring 15 to norapparatus with an improved electric heating elemally close said apertures 13 50 ment which will facilitate the control of the heat Suspended from the lid and insulated thereaccording to available voltage of the electric from is the electric heater 17 adapted to project source or available quality of water used for downwardly in said receptacle and be submerged evaporation. in the liquid to be evaporated.

Its outer with a comparatively narrow tubular nozzle 12' end 27a is formed to a grasp whereby the rod extending obliquely in a forward and upward can be easily manipulated from above the lid 11 direction; 'At its forward open end this nozzle of the receptacle. The rod 28 extends at the rear is reduced to a very narrow passage. The safeof the terminals 22 and is so spaced from the latty valve 13 comprises a cap 13' having a head ter as to leave suflicient clearance for the plug 55 piece formed with an interval central vertical P when engaging the terminals.

Instead of the vertically movable rod 28 for raising or lowering the sleeve 24 we may use the construetion shown in Figs. 3 and 4. Here the opening in the ear piece 26 of the ring 26 is so shaped as to threadedly engage a spindle 29 having multiple serpentine threads. The lower end 29' of this spindle 29 is journalled in a plate 30 fixed on the ends of the rod 20 and its upper part is rotatively borne in a bearing 31 projecting from the lid 11. This upper end of said spindle projects through the lid and carries a lever or handle 32. On a dial disk 33 fixed to the upper face of the lid are provided a plurality of notches 33 and 33 etc., arranged in a circular series and which are adapted to engage a suitable catch 34 projecting from the lower face of the lever 32 so as to hold the screw spindle 29 against rotation from its adjusted position.

It will be clear that whenever the available voltage of the lighting system or the mineral contents of the water to be evaporated require reduction or increase of the acting surfaces of the two carbon electrodes this can be easily and quickly accomplished by the adjustment of the glass sleeve either by the rod 28 or by rotating the spindle 29.

The receptacle 10 may be suitably supported on the base 35' Ma stand 35 provided with a handle 35*.

In the present embodiment of our invention the stand is made in form of a casing in which the receptacle 10 tightly fits. The casing on its circumference may have vertical rows of perforations or windows 35 through which the level of the water or other liquid contained in the receptacle may be observed. The electric cord or cable p carrying the plug P may be passed through a hollow 35* of the handle 35, as is shown in Fig. 1, and be movably borne therein for convenience of transportation.

As a vaporizer our apparatus operates in the well known manner, as follows:

The receptacle 10 is filled so that the electrodes 18, 19 are immersed in the water or other liquid used for evaporation. The filling and refilling can be done through the opening 11 on removing the safety valve 13 from the headpiece 12. On connecting the cable or cord p to the lighting system or other source of electrical energy and applying the plug P to the terminals 22 "the circuit will be closed through the liquid and two carbons constituting the positive and negative carbon or heating resistances, whereby the liquid will be heated to evaporation. The vapors will pass out through the nozzle 12'.

To usethis apparatus as a diffuser, sprayer, atomizer or exterminator we. provide the following means:--

Suspended from the stand or casing 35 is a second receptacle 36 which may contain the liquid or chemical solution desired for the particular pur- In the present embodiment this receptacle is in form of a relatively narrow cylindrical flask the lower part of which is frictionally or otherwise supported in a loop or ring 3'7. This ring is provided with a hook shaped projection 38 which is adapted to be slipped through a recess 35 provided at a lower part of the front face of the easing 35 and which hook will removably engage the lower edge of the recess and thereby support the flask in position.

The flask is provided with a lid 39 threadedly engaging the neck of the flask and which advantageously may have a concaved upper face 39 provided with an aperture 39 Leading into this receptacle through the perforation 39 is a syphon or suction tube 40 whose upper end 40 projects outwardly and is fixed in a frame or member 41 projecting from and fixed to the nozzle 12. The frame 41 is in form of a trough or plate of U shaped cross section which at its upper end is perforated to engage around the reduced end of the nozzle 12' and to be soldered or otherwise permanently fixed thereto. The frame 41 extends from said nozzle in a downwardly and forwardly inclined position and has fixed to it or is formed integrally with a member 42 which projects from its upper face. This member 42 is provided with a bore 42' through which extends and in which is permanently fixed the upper end 40 of the tube 40. The lower opening of the tube 40 terminates near the bottom of the flask, while its upper opening is flush with the front opening of the nozzle 12', which for the purpose of producing a very fine jet of vapor is made very narrow.

When vapor passes out through said nozzle, it will in passing over the upper opening of the tube 40 create a suction therein, as a result of which liquid contained in the flask 36 will rise through the tube and be injected into the vapor and become diffused with it.

Condensed fluid will flow down the channel or trough accumulating on the surface 39 of the lid 39 and through the opening 39 drop back into the flask 36.

To regulate the stream of liquid passing out 105 through the tube 40 we provide a suitable needle valve 43 threading in the member 42.

In the modification shown in Fig. 6, the trough 41 may have its upper face covered by a plate 44.

It is, of course, understood that various changes 110 may be made in the apparatus without departing from the principle of our invention.

We, therefore, donot wish to restrict ourselves to the details shown and described.

What we claim is:--

1. In a diffuser or the like, a vaporizer having a vapor discharge, a liquid receptacle external of said vaporizer and a tube suspended in said receptacle to be submerged in the liquid thereof and whose outer end terminates in front of and flush with said vapor discharge so that when vapor issues from said vapor discharge the liquid will be drawn into the vapor and be diffused with it.
